How to rotate a triangle counter clockwise 180 degrees

The video tutorial explains the concept of 180-degree rotation in geometry, emphasizing that the direction of rotation (clockwise or counterclockwise) does not affect the outcome. It demonstrates how to transform coordinates by negating both the X and Y values to achieve this rotation. The tutorial includes practical examples and verification using a sheet of paper to ensure understanding.

Describe the transformation of the points L, Q, and P when they are rotated 180 degrees.

How can you confirm the accuracy of a rotation using a sheet of paper?
